Work: Calculate the value of equation (4.2+3.5+0.2)*(4.2+0.2)*2*2+(1.4+2.7+0.6+0.9)*(2.7+2.1+0.2)*2 .
Question type: Mathematical calculation
Solution:
(4.2+3.5+0.2)*(4.2+0.2)*2*2+(1.4+2.7+0.6+0.9)*(2.7+2.1+0.2)*2
=7.9*(4.2+0.2)*2*2+(1.4+2.7+0.6+0.9)*(2.7+2.1+0.2)*2
=7.9*4.4*2*2+(1.4+2.7+0.6+0.9)*(2.7+2.1+0.2)*2
=7.9*4.4*2*2+5.6*(2.7+2.1+0.2)*2
=7.9*4.4*2*2+5.6*5*2
=34.76*2*2+5.6*5*2
=69.52*2+5.6*5*2
=139.04+5.6*5*2
=139.04+28*2
=139.04+56
=195.04
Answer:(4.2+3.5+0.2)*(4.2+0.2)*2*2+(1.4+2.7+0.6+0.9)*(2.7+2.1+0.2)*2=195.04
